ABSTRACT:
A wire drawing die having improved physical properties, and a blank therefor. A cemented metal carbide support component having a lengthwise extent is provided to extend radially about a central longitudinal axis to define an internal bore therethrough. For receiving the wire to be drawn through an internal thereof, a sintered polycrystalline compact component is received within the bore of the support component. The compact component is bonded to the support component at an interface surface extending along the longitudinal axis from a first end spaced a first local maximum radial distance from the axis to a second end spaced a second local maximum radial distance from the axis. The interface surface is radially symmetrical about the longitudinal axis and extends radially inwardly from the first and the second end to define an intermediate region therebetween spaced a local minimum radial distance from the axis.
